Yes, but only a dry crumb now and then. Plain Weetabix is 95% wholegrain wheat with a little sugar and salt, so a dry piece the size of your little fingernail is fine for a Syrian hamster once in a while. Never give it soaked in milk, which Burgess warns against, and skip flavoured, chocolate or sugary kinds.
| Safe? | Sometimes: plain and dry, as a rare treat |
| How much | A dry piece about 1 cm (0.4 in) across for a Syrian, a crumb for a dwarf |
| How often | Once a week at most |
| Best served | Dry, straight from the box, original only |
| Watch out for | Milk, flavoured versions, soggy pieces in cheek pouches |
Is Weetabix safe for hamsters?
Plain Weetabix in a small dry piece is safe. No charity writes about Weetabix by name, so we have reasoned from what the ingredients are and what hamster charities say about grains. Weetabix lists its ingredients as wholegrain wheat (95%), malted barley extract, sugar, salt and added vitamins and iron. The Bunnyjackpot Foundation, a UK small-pet rescue, lists grains as safe for hamsters, and Woodgreen lists cereals as a healthy treat.
The caution comes from Burgess, a vet-led pet food maker, which warns that high-carbohydrate human foods such as bread and biscuits can cause digestive problems, and Omlet, which says to avoid processed food made for people. Weetabix is less processed than most cereals, but it is still a starchy human food with nothing your hamster's dry mix lacks, so we keep it rare.
How much sugar and salt is in Weetabix?
| Per 100 g (3.5 oz) | Weetabix Original |
|---|---|
| Carbohydrate | 69 g |
| Sugars | 4.2 g |
| Fibre | 10 g |
| Protein | 12 g |
| Fat | 2.0 g |
| Salt | 0.28 g |
Figures are from Weetabix's own UK product page. One biscuit weighs 18.75 g (about 0.7 oz), far more than a hamster's whole day of food: Woodgreen suggests only about 10 g of dry food a day for a Syrian and 5 to 8 g for a dwarf. That is why a fingernail-sized piece is plenty.
How to give Weetabix to a hamster
- Check the box. Original Weetabix only, not chocolate, golden syrup, fruit or protein versions.
- Break off a dry piece. About 1 cm (0.4 in) across for a Syrian, a crumb for a dwarf.
- Serve it dry. Never with milk or water. Soggy cereal sticks in cheek pouches and spoils.
- Take it off the day's dry food. Give a little less mix that day, so the treat does not add up.
Weetabix with milk, flavoured Weetabix and Weetos
- With milk: no. Burgess calls dairy particularly dangerous for hamsters.
- Chocolate Weetabix, Weetos or chocolate cereals: no. Chocolate is dangerous for hamsters.
- Golden syrup, honey or fruit versions: no. Extra sugar, and dried fruit is sweet and sticky.
- Weetabix Minis and Crunch: skip them. Many contain added sugar or fruit.
Who should skip Weetabix?
Dwarf hamsters, especially Campbell's and winter whites, which the PDSA says are prone to diabetes, should have only a crumb, or none. Overweight hamsters should go without.
Better treats to try
For a grainy treat, a few grains of plain rice or a piece of plain popcorn work just as well. Our pages on bread and crackers cover the other cupboard staples. See our list of what hamsters can eat, our hamster diet guide and our hamster care guide for the rest.
Weetabix questions
Can hamsters eat Weetabix with milk?
No. Burgess, a vet-led pet food maker, says dairy is particularly dangerous for hamsters, and soggy cereal can stick in cheek pouches and spoil. If you share a crumb of Weetabix, give it dry, straight from the box.
Can dwarf hamsters eat Weetabix?
Only a crumb, rarely, or not at all. Dwarf hamsters eat only 5 to 8 g of dry food a day, according to Woodgreen, and Campbell's and winter whites are prone to diabetes. A starchy human cereal is a poor use of that small appetite.
Can hamsters eat Weetos or chocolate Weetabix?
No. Both contain chocolate or cocoa, which is dangerous for hamsters, plus added sugar. If your hamster ate some, take away what is left and ring your vet for advice, especially if they ate more than a crumb or seem unwell.
Is Weetabix better than bread for hamsters?
Slightly, because it is dry, mostly wholegrain wheat and fairly low in sugar, so it is less likely to stick in cheek pouches. Neither is a food your hamster needs. A small piece of either, now and then, is a treat, not part of the diet.
